An HTML file, often found with the extension htm, is a hypertext markup language file. Html is a text-based markup language (markup: award), which is mainly used for websites.
In addition to the actual content to be displayed on a web page, an HTML file also includes awards for how to display and structure something. For example, HTML also includes images on the website and defines which text is a link and where it should lead.
